If you are a fan of mid-century modern, I would recommend 'Visual Acoustics:The Modernism of Julius Shulman'. Some great shots of iconic modernist architecture and an interesting story about the life of the well-known photographer.

A new film , 'How Heavy is Your building, Mr Foster?' (Dejan Sudic (sic)) has just got a limited release in UK. I imagine it will be on DVD soon. From a couple of interviews it sounds interesting.
Also, Sketches of Frank Gehry is OK.

I also enjoyed "Objectified" and "Helvetica" by Gary Hustwit. Even though they are not really movies about architecture, they sort of fall into the larger creative corner. He's also shooting a new movie on city planning and design called "Urbanized".
